Before you speak to a single agency, decide the one business number that matters most for the next six to twelve months. For a service business it is usually qualified enquiries. For a store it is orders or revenue from a channel. For a subscription product it might be trials that turn into paying customers.
Write it down in one sentence, for example: "We want more qualified enquiries from Delhi NCR at a cost we can afford." That sentence is the brief. An agency that cannot connect its work to it is selling activity, not results, and you will find it hard to judge them later.
Try not to give an agency five goals at once. Brand awareness, lead generation, app installs and follower growth need different work and different measures. Pick a primary goal, and list the others as secondary.
"Digital marketing" covers very different jobs. It helps to know which of these you are buying, because few agencies are equally good at all of them.
Often the biggest gain is not more traffic but fixing what happens to the traffic you already have: a slow site, a confusing checkout, a broken tracking setup, or leads that nobody follows up. That is why an honest agency asks to look at your current setup before selling you more of anything.
Start with three to five agencies rather than twenty. Look for evidence that they do the kind of work you need, for businesses like yours, and that the people you will speak to are the people who will do the work.
Reach, impressions and follower counts are easy to report and easy to inflate. What you want is a small set of numbers that link to money: enquiries, orders, cost per acquisition, revenue from each channel.
Ask which numbers will be reported, where each comes from, and how they will be checked against your own records. A useful test is whether the figures in the agency's report agree with the figures in your bank or CRM. Good tracking is set up before spend is scaled, not after, because otherwise nobody can tell what worked.
Ask this early: "If the report says we got 100 leads, how do we confirm that in our own systems?" A good agency will answer without hesitation.

Ask who will plan your campaigns, who will build or fix the website, who writes the content, and how those people work together. When the site, the ads and the social channels are split between different teams or different agencies, nobody owns the result, and messages get lost between them.
It also matters who you will speak to. Some agencies sell with senior people and then pass the work to others. Ask to meet the person who will run your account, and ask how often you will speak.
This is the single most common source of trouble when a relationship ends. Before you sign, confirm in writing that the following stay in your name, with the agency added as a user:
If an agency insists on running your ad spend through their own accounts, ask why, how you will see the real spend and results, and what happens to the data if you leave.

Pricing models differ, and each has trade-offs. None is automatically better; what matters is that you understand it before you sign.
Ad budget is separate from agency fees. Ask for a simple breakdown showing what goes to the platforms and what goes to the agency, and how any change in scope is priced.
A useful proposal is specific to your business. Expect to see:
Be cautious of proposals that are mostly generic slides about digital marketing, or that promise a specific ranking, follower count or number of leads without having looked at your business.
A sensible way to reduce risk is to begin with a limited piece of work instead of a long retainer. A written audit of your site, tracking, ads and search presence shows how the agency thinks and gives you something concrete, whether or not you continue. If it lists problems ranked by how much they cost you, and a recommended order of work, you can act on it yourself or with anyone else.
Set expectations for the first three months so both sides know what good looks like.
Keep a monthly review meeting with a short written summary. Paid channels can show useful signals within weeks. Search engine optimisation usually takes longer to show results, and anyone who promises exact dates is guessing.
There is no single right number. A sensible approach is to work backwards from your margins: how much you can afford to pay to win a customer, and how many customers you need. An agency should help you set a budget from those numbers rather than suggest a figure before asking about your business.
What matters more than location is whether the agency understands your market, communicates clearly and can show relevant work. Some businesses like meeting in person; many work well remotely as long as there is a regular review rhythm.
One team covering the website, media, social and automation avoids gaps and finger-pointing, because someone owns the whole result. It only works if that team is genuinely good at each part, so ask to see evidence for each.
It depends on the channel. Paid ads can show signals within weeks once tracking works. Search engine optimisation usually takes months. Website fixes can help conversion as soon as they are live. Be cautious of anyone promising exact timelines.
